How Much Does Basement Waterproofing Cost?

If you’re asking about basement waterproofing cost, you likely have a wet basement, standing water, or have recently purchased a home that shows signs of water intrusion and you’re concerned. Water intrusion into your foundation walls is serious business. Left unchecked, it can affect the structural integrity of your home.

We often get asked “How much does basement waterproofing cost?” The answer is different for every homeowner because each house is unique. Some factors that impact the final cost of professional waterproofing include:

  • The size of your home
  • The cause of the water intrusion
  • The extent of the water damage (cracks, bowed walls, etc.)
  • Your future plans for the basement (remodeling or adding a bedroom)
  • The recommended solution

Since we specialize in interior basement waterproofing solutions, that is what we will address in this article. Exterior basement waterproofing will cost thousands of dollars more for an existing home because it involves excavating around your home’s foundation.  In addition, we prefer interior solutions because we can offer a more comprehensive warranty and we have seen people spend thousands more on exterior solutions that don’t work.

Professional Basement Waterproofing Cost

You’re here because you want to know what basement waterproofing companies are going to charge you. Once again, the final cost depends on your specific situation, but for the installation of a French drain system and one or more sump pumps, the national average is $40 to $85 per linear foot or $3,000 to $12,000. The larger the perimeter of your home, the higher the cost.

A French drain system diverts groundwater to your sump pumps before the water has a chance to show up on your basement floor. After removing a perimeter strip of the concrete floor, workers dig a trench around the interior foundation next to your foundation walls and often foundation footing.  They then put down gravel, perforated drain pipe, tiles, and a sump pump basin. Then the pipes are connected to one or more sump pumps. Often these systems are called interior footer drains, interior french drains, or interior water pressure relief systems.

If there are cracks in your foundation that need to be repaired, that is an additional cost. That cost could run between $2,500 and $5,000 for major repairs and $500 or more for basic repairs.  Some companies go the extra step of putting a plastic vapor barrier or liner on the interior walls tucking into the drain below to direct wall seepage to the drainage below.

These are ballpark figures, and only an in-person basement inspection can result in a good estimate. And be aware that once work starts, if additional problems are uncovered, and the scope of work changes, the cost could go up. This is true no matter what basement waterproofing company you hire.
